Effect of phospates on the oxygen levels in pond water
Division:Health Sciences
Region:South Fraser
City:Surrey, BC
School:Khalsa School (Surrey)
Abstract:Effects of phosphates on dissolved oxygen levels in pond water was determined. I filled 6 jars with same amount of water but added different amounts of phosphate to each, except the constant. The temperature, sunlight and other factors were kept constant. My results showed that oxygen levels increased due to algae growth, and this proves that once the algae die the oxygen will be consumed.
